Permanent magnet linear generator for renewable energy applications: Tubular vs. four-sided structures

While the exhaustion of carbon based fuels has become a certitude, the use of alternative fuels became more popular in the last decades. The renewable energy sector emerged, providing an alternative to conventional energies; amongst them the wind and solar energies became extremely popular in the last decades, supplying important parts of the total energy required in countries like Germany or the United States of America. Besides these, the wave energy sector represents a huge, yet unexploited domain, which could prove to be a long time solution for the forthcoming energy shortages.
